For the sake ofclearness, these various parts of the machine will be described more orless separately.

The paper feeding and cutting mechanism.

- vThe. paper is preferably supplied to the machine Vfrom a continuousstrip and pastel orglue is applied to one side thereof, but as "thispart of the mechanism is immaterial to the present invention, nodetailed description of the same 1s necessary. It 1s sufficient to notethatl the shaft 13 on its endopposite the-shaft llis provided with abeveled gear 14' which cooperates with av corresponding gear '14 on atransverse shaft 14h carrying a roller 14c on which rests an idle roller14d` journaled in the brackets 14e. The shaft 14h is connected bysuitable gearing 16' to a second transverse shaft 17, the latter beingprovided with a roll 18 which extends downwardly into a glue pan Pf TheVroll 18 serves Vto apply glue to one side of the paper which isled intocontact therewith from a supply roll (not shown). After being thussupplied with glue, the paper is led over certain idle rolls (not shown)and is then caused to pass between the rolls 14;, 14d and into themachine. i Y In passing'into the machine, the paper is led between thecooperating rolls 19 and 2O which are journaled in suitable standards 21on the tablel'O. IThe rolls 19 and 2O are rotated intermittently andconstitute measuring feed rolls, lor in other words, these rolls at eachoperation serve to feed a measured amount of the paper into the machine.The rolls 19 and 2O are provided with suitable shafts ywhich arereceived in slots 21 Vof the standards 21, the upper roll 19 resting bygravity on the lower roll 20. The ends of the rolls 19 and 20 or theshafts of theV same, are provided respectively with kgears 19, 20meshingwith each other, the

gear 20 meshing with a pinion 22 rotatable on a stub shaft 22 secured inthe standard 21andrigid with a large gear wheel 22b which is driven froma pinion 23 rigidly secured toa beveled gear 24 which in turn is `paper'is caused to pass. :clude a plurality of upper strips 30 whichrotatedfrom the mutilated beveled gearwheel 25 secured to the shaft 13.`The beveled` gear wheel 25 is rotated continuously but the connectionbetween this gear and the rolls 19 and 2O is such that the rolls aregiven anl intermittent rotation. The gear 25 has beveled teeth 25 on apart only of its periphery, as illustrated particularly in Figure 11.Outside of the gear teeth 25 the gear wheel is provided with a flatsurface 25'). A member 26 is arranged between and rigidly associatedwith the gears 23 and 24 and is formed with aflat surface 26a. This flatsurface cooperates with the flat surface 26 formed on the member 26.lThe fiat sur- @face 25" of the gearrwheel 25 is provided with-adepressed portion 25 as illustrated particularly in Figure 11. F romthis it will be understood that as the gear Wheel 25vro-` tates, thecooperating gears 24 and 23 and the rolls 19 and 20 will be driven solong as thefgear teeth 25 on the wheel 25 are in mesh with the teeth onthe gear Wheel 24:. Then the'wheel'25 rotates to the extent that theteeth25 are no longerl in mesh with the teeth on the gear 24, the member26 ywill have been rotated to ai Isufficient extent that I i the flatsurface 26a thereof will come in contact` with the flat surface 25b onthe gear wheel A2,5. l This` servesV to lock the pinion Y and-gear 23,24and consequently the rolls 19 and `20 against further rotation untillthe gear wheel 25 has rotated a sufficient degree toY again bring theteeth 25 thereof into engagement with the beveled gear 24 whereupon thisgear together with the rolls 19 and 2O will again be rotated.

It will be understood that the intermittent rotation of the rolls 19 and20 thus produced is sufficient at each operation to feed the desiredamount of paper into the machine.'

Cooperating with the -feed rolls 19 and 2O are longitudinal guidesbetween which the These guides inare secured at one end to across bar 31and at the other end to across bar 32, the former beingsupported in thestandards 21 and the latter' being arranged to rest on lower guidestrips 33 which are also secured together by 'means of a cross bar 311also supported in any suitable manner on the standards 21. The paperpasses between the guide vstrips and 33 and beneath the cross bar 32.

As the paper is thus fed intermittently to rthe machine, itis cut intoshortv pieces or strips of a length corresponding to the length of thetubes to be formed. Such cutting operation is performed'by-means of amovable cutter 35 extending transversely of the machine and cooperatingwith a stationary cutter 36 over which the paper is adapted to pass. Thecutter is pivoted at 37 Vintermediate its length to a bracket on the.table- 10 and the same is iUntermitteilt-ly.,1op:l eratedby means ofa-caInBS mounted onthe shaft; 13, the cuttenbeing provided with roller353i' Whichis held? in"V constant engagement;` with the cam, 38'by meansot a! coiled,

The sheets of paper ortube blanks` cut` connected to a lever 4t2-Whichis` also pivoted intermediate its length on the standard 4.1. TherfreeendI of the lever 42 is arranged/adjacent theshaft 13 and is providedVwith a roller adaptedI to bear against a cam 43A securedto said shaft.A coiled spring 444 is also connected to the lever 42y and. normallyexertsa downward pressure upon the end of the same opposite the eam 43.From the foregoing it'will be seenthat as the shaft 13 rotates the lever42 Willbe' operated soas to hold the y tilting 'platform 40 'in Yasubstantially horizontal position las a sheet or blank eut from thestrip is deposited thereon, after which the platform vvillrbe tilted'into the position shown particularly in Figure 3. The platform not onlyhas a tiltingemovement but has a slight bodily movement up 'and down-andalso a slight! lateralv movement as'Y it is tilted downwardly. Toeifeetthis re.- sult, the upper end of the standard 41 has a diagonal slot 41formed therein and the platform 40 on its under side has a pro# jeetion40 carrying a pin 40 which slidably engages in the slot 41jL of thestandard. i hen the platform 40v is raisedfinto hori- Zonta] posit-ionby the lever 421. the pin 4Gb Will' slide up the inclined slot 41nso-that `the platform Will be positioned Close to the lower cutter 36 toreceive the sheet o rblanksev ered from the strip. The paper strip isted into lthe machine so that the sheet or blank cut therefrom willextend a slight vdistance beyond o1` project over the lower or lefthand,end of the platform.` This is shown particularly in Figure 13 ot' thedrawing. After a sheet or blank 'has been deposited on the platform; 40krand as the same is moved downwardly. `it Will also be moved toward theleft in Figure 3 so that-the projecting' edge orf the blank will be`placed in position to be engaged by the ltube Winding mecha'- nism. A I

In order to hold the sheet orblank on the platform 40 while the latteris being moved downwardly and laterally, means are'p'rovided forclamping the same against Vthe platform- 4Q.' This means-,comprises1L-leiter,

That shown comprises a mutilated gear Wheel 57 on the Ashaft 15', whichmeshes with a pinion 58 on a stub'shaft `5,9 carried .by a bracket 59a.The pinion 58 is rigidly connected to a `gear Wheel 60 which in turn41.1.0 the spindle vx'v-herelay, the,

meshes With a longlpinion 61 ,on the spindle v shatt- 5'5. The gearWheelf57`is provided with teeth throughout aA part` onlyV of itsperiphery, the remainder 'of itsperiphery being smooth or untootlie'd.x/Vhen the toothed portion of this gear wheelengages lthe pinion 58 thelatter, togetherniththe gears 60, 61 and shat 55, Will be rotated.r`'When the untoothed portion of gear. wheel 5T is adjacent :the pinion68,' the latter of thelever 45 extends toa pointadjaent not lie/rotatedl'At such time the pinion 58 isf-locked againstv rotation. To accomplishthis, the pinion is provided on one side with a laterally projectingportion 58,vone edge of which is formed with a concave curvature58""corresponding to theV curvature of the outer edge ofthe gear Wheel57` The gear wheel 57 isalso provided on one side with a laterallyprojecting portion 57 a, the edge of which at 57h is convexly curved tolitthe concave curvature 58" on the pinion 58. The curved edges 58" and571 thus cooper* ate to lock the pinion 58 against rotation when theteeth on the gear Wheel 57 are not in mesh with theteeth on the pinion58.v

`It will be understood that each time the shaft 55 and spindle 56 arerotated the amount of rotation is suliicient to Wind the sheet or blankseveral times around the spindle and as the blank is provided on oneside with adhesive as previously noted, the result'will be the'formation ot altube T on the spindle 'as illustrated in dotted lines inFigure 5. c Y v In'order to insure that the paper shall be Wound `tightabout the spindle 56 and pressed down against the same, there isprovided arwiper or presser' 70 which is ,connected to" a. benti arm 71pivotallyl connected at 72 to a bell crank lever 73 pivotally v mountedat 74 onl the tablelO. A earn 75 on .roller on the bell crank lever 73and thereby tilt the same and move the bent Aarm 71.

l/ Vhen the high portion of the cam 75 is operating against the lever73, the .a1-m71 and Wiper will be moved so -that the latter will be outof engagement with the spindle 56. When the low part of the cam iseffective, the lever 73 is drawn down by means of a coiled spring 76anchored thereto and to the table 10, with the result that the Wiper 70is moved into position adjacent the spindle 56, in which position itbears against the paper being Wound upon the spindle and wipes orsmooths down the same so as to insure the proper formation of the tube.yThe bent lever 71 is made slightly yieldable by means of a spring 71ainterposed between the same and one arm of the bell crank 73. Thecompleted tube is oit the character illustrated at T in Figures 15 and16.

T 71e bag feeding and inserting mechanism.

After a tube is formed as previously described, a 'bagB of explosivematerial, as illustrated in Figure 16, is inserted in the tube While thesamereinains in position in the machine and before it is ejected there-Vfrom. To accomplish this result, the machine is provided With an endlesscarrier 8O which is made up of a plurality of rectangular blocks 81connected by sprocketL links 82, the links being pivotally connectedtothe blocks. The carrier 8O is operated by means lto rest directlyabove this opening. Aother Words, as the endless carrier-1s moved ofV anpair of vsprocket wheelsf83 around which it passes, the vother end ofthecarrier passing aroundasimilar pair of sprocket Wheels (not shown).v Thesprocket wheels 83 are mounted on a short shaft 83asupport `carrier 8Ois given a stepvby stepmotion.

- Each of the bloeks81 ofthe endless carrier is provided 'With arectangular pocket or slot 81 which extends therethrough fromV t .thetopto thebottom of the block, the tops oi" these pocketspreferably-being liared asl illustrated at 81b'particularly in Figures4and12. w W,

The pockets 812L are intended l.to receive the bags B ot explosivematerial, illustratedjin Figure 16, and the bags may tbe deposited inthese pockets byhand orvin` any other n'ianner desired. As, the bags aredeposited inthe pockets ot thebarrier,,theyare, of course', moved along.Withthe carrier. j

Arrangedbeneath the upper portion of the carrier 80` is a tubularmagazine89 which ismounted Vin a block 89l supported yon a standard 891on `the tablelt). The magazine 8,9 is provided'onfits upper side withv aslot or opening 89?, and .the end-thereof adjacent the spindle 56 isslightly rtapered as shown at 89d .for a purpose later described. Themagazine 89 is so arranged Athat as the carrier 80 is moved over thesame, the pockets in blocks 81 will successively conIie n step by step`in the manner previously described, one of the pockets in blocks 81 Willliel above the 'opening in the .magazine 89 whenever Vthe carrier is atrest.

To :torce the bags ot'l explosive material from the carrier 80 into themagazine 89, there isV provided a main plunger 90 andan auxiliaryplunger 91; These plungers are arranged vto slide up and doivn insuitable guides 92 secured to the table 10 and the same are carried atthe end ot a rocking arm or lever 93 pivoted at 94 to av standard 95 onthe4 table. The lever 93 is operated by means of a cam groove. 96aformed in the face of a cam wheel 96 seeuredtothe shalt 11, the leverbeing provided With asuitable roller 93a engaging-the cam groove.l It`1s is ofl sufficient length to 'torce abag of explosive material fromthe pocket 81L into the c ,tubular magazine 89.` The' auxiliary plungerLoodsen- 91-serves the purpose of partially forcing the bags ofexplosive material throughythe pocketsy 81a. It is, of course, to beunderstood that the plungers 9 0 and' 91 are oper ated in timed relationwith the step by step movements ofv the carrier 80 so v that theplungers are caused to move downwardly during the intervals that thecarrier is at rest.

Normally the tubular magazine 89 occupies a position slightly removedfrom the position occupied by 'a tube T which is formed on the spindle56. Preparatory to forcing the bag of explosive material into the tubeT', it is desirable to move'the magazine against r into close proximityto the tube. To accomplish this result, the block 89 of the magazineisslidably mounted on thek standard 89b and is operated so asy to move aslightdistance into contact vwith the tube T on the spindle 6 after suchtube is formed and just before' the bag is forced from the magazine 89.Such movement of the magazine is effected by means of a cam 100 securedto the shaft 15 and arranged to contact with the end of a bell cranklever 101 pivoted at 102 and the end of which engages a bearing plate103 secured to the block 89a. The cam 100 is made with a very slightthrow so that ythe movement o f the magazine 8 9 will b e very slight,only a fraction of an inchbeing sufcient to enable the tubular magazineto bebrought into contact with the tube on the spindle.

The magazine 89 is arranged substantially in axial alignment with thespindle 56 and, as above noted, the end of the magazine is made slightlytapered as indicated at 89d. Such tapered portion is adapted to projecta slight distanceinto the tube T which assists in supporting the tubeafter the spindle 5 6 is withdrawn, as hereafter described.

To force the bags from the magazine 89, there is provided a plunger 105which is z adapted to move axially through said tubular member. Thisplunger is slidably mounted in. a standard'106 supported on the thatrotation of the shaft 13 will cause the plunger 105 to movez axiallythrough the tubular magazine 89 to force a bag'ofexplosive materialtherefrom into a tube T and it is, of course, to be understood that theparts vare so timed that the 'plunger 105 will beI caused to operate inproper timed relation with the other parts of the mech anism.4

Before the bag of explosive material can bey forced; into the tube T, itis, of course,

necessary that the spindle 56 be withdrawn therefrom.y Such movement ofthe 'spindle 56 is effected through the medium of a cam groove 110formed in the face of the cam disk 96, this groove being engagedv by aroller 111 on a rocking arm 112 pivoted on the table 1'0, the arm 1'12also carrying a second roller 113 which is arranged between two with theadvance of the magazine 89 and the plunger 105i to force the bag ofexplosive inaterialinto the newly formed tube T. As the spindle 56finishes rotation and is with-` drawn, the tube T abuts against thestripperl block 561 to strip the samel from the spindle. The long pinionv61 on the shaft 55 permits constant engagement 'between suchl pinionand the gear wheel regardless of the axial' movement of' the shaft 55. jf 1 `To insure that the tube T will be ejected or knocked out ofposition after the bag of Vexplosive material is inserted' therein,there is provided' an ejcctor115' which is normally positioned above thespindle 5'6 and which is operated by means of a lever 116 pivoted at117' to an arm on theta'ble l0, the intermediate portion of this leverbeing provided' with a member 118 which cooperates with a cam119'secured'` tothe shaft 15j. A spring 120 tends to draw the lever 116downwardly and' the cam119 is providedV with a low por tion whichpermits such downward movement when this portion comes beneath thebearing member 118; The cam 119 is so shaped that the arm 116 is causedto move down quickly and the ejector 115 thus acts to eject thecompleted lirecracker from the machine. I

After one lirecracker is ejected, thespin` dle 56 again advances and asit does so the next blank kor sheet is in theposition shown in Figure 13and' the end thereof is engaged I by the slot 56n of the spindle. Thespindle ist again'given" rotation lto wind anew tube andthe variousoperations are thus repeated in proper sequence and timedl relation'.

lt is obvious thatl the details of the mechanism may be varied to alarge extent and the invention isnot to be understoodl as limitedto theparticular arrangements shown and" described except as required: intheappended; claims.
